A Workshop on Acoustic Fluctuations in the Ocean, sponsored by NAVELEX 320 was held at the Naval Research Laboratory, Washington, D. C. on Feb. 22-23, 1978. The theme was (1) to highlight the relation between requirements of system performance models (APSURV, PSEUDO, APAIR, etc.) and current research on acoustic fluctuations conducted by Industry and the Navy (2) to find ways to establish closer cooperation between Researchers working in the field, and Users of research results (3) to recommend programs. This memorandum summarizes the agenda and key technical issues of the Workshop, and contains all papers presented. It also gives a brief history of previous Workshops on this subject, and a technical review of acoustic fluctuations in general. Recommendations for programs are scheduled to be made available in a separate publication.
